A browser extension that formats, validates, and syntax-highlights JSON in the browser with collapsible trees.
JSON Viewer makes raw JSON responses readable. When you open an API endpoint or a .json file, the extension renders it as a collapsible, syntax-highlighted tree instead of one long string. You can expand and collapse objects, search within the document, and copy individual values. It also surfaces parse errors, which is invaluable when debugging a malformed response. Developers working with APIs use it constantly, and it works on the raw JSON URL you open directly in the browser. Free, light, and just works.
